Slag pump is a kind of gear pump, its mechanical seal with slag pump seal is also called the face seal device and discussion, he is to rely on spring and the pressure of sealing medium in reverse ring and static ring contact appearance on appropriate clamping force, is the two end face tight fit.Insist on a very thin layer of oil film between end face, medium through the resistance is very big, to prevent liquid leakage, thus to seal the goal, at the same time have smooth influence on ring and static ring.Adjust well to complete without leakage.

The characteristics of the mechanical seal: slag pump mechanical seal of fault disposal and discussed primary virtue of mechanical seal is sealed, in a cycle, little leakage;To humanize the long life, common to use 5 years you;Maintenance cycle is long.But complex mechanical seal structure, built in, the repair is always to put the oil transfer pump mechanical seal to stop the collapse, big workload.Therefore, ensure reliable mechanical seal, and delay the use of mechanical seal and life is very main.

Mechanical seal in the daily operation, prone to a lot of problems.To attack is the first problem of mechanical seals leakage amount in excess of the difference and the temperature is too high, touch mechanical seal gland, if can't stay in the above, to clarify the temperature too high.Leakage quantity of each side should not exceed 60 drops/min. If flows into linear, are elucidated, large amount of leakage of can be sure they can see;If oil outward, should immediately stop checking.
